i have bought the Nav at 125,000 kms and in the past 5 months have noticed a slow and increasing in loudness a thud on the l/H side front wheel as i thought. i have changed front shocks, bottom ball joints, control arm bushes and sway bar rubbers thinking that i would eventually get rid of it, but to no avail. it stared happening firstly when i would be going into a drive way or around a roundabout, but now it happens even travelling on a straight road, i am losing my mind and wallet with trying to pin point the issue as well as my mechanic. then sometimes i think it is coming from the rear of the vehicle, can someone HELP me please with any suggestions please. Rod.
